EDWARD WVILLIAM GOODRICK, OF APPLETON, WISCONSIN.

BARK-ROSSING MACHINE.

Specification of Letters Patent.

Patented Dec. 11, 1906.

. Ap li ation m January 8, 1906. Serial N... 295,049.

To all whom, it inc/y concern.-

Be it known that I, EDwAnD WILLIAM-Goon- RICK, a cltlzen of the Unlted States, and a resident of Appleton, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Bark-Rossing Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in certain peculiari ties of construction and combination of parts hereinafter particularly set forth with reference to the accompanying drawings and subsequently claimed, its object being to improve bark-rossing machines of the kind employed in the preparation of log-sections, commonly termed blocks, for the reduction of same to paper-pulp, the improvement having especial reference to adjustment of the blockrest of such a machine.

Figure 1 of the drawings represents a side facing the aperture aforesaid. The shaft is.

herem shown provided with tight and loose pulleys E F for a driving-belt; but any suitable means may be employed to drive said shaft. A stop-gage G is shown in adjustable connection with the front of the hood B adj acent to one end of the aperture in same, and as thus far described the machine is similar to those of common knowledge for the purpose above specified.

In accordance with my invention the front of the machine is provided with a lower cen tral vertical rack H and a pair of vertical guides I for parallel bars J, equidistant from the rack. The vertical bars are provided with upper arm extensions K, herein shown at right angles thereto toward the operator of the machine. Extending through the arms is a rod L, provided with collars b, that abut the inner sides of said arms, and nuts 0 are run on the ends of the rod against the outer sides of the aforesaid arms.

Bolted to lower lugs 01 of the bars J is a front plate M, having a central aperture, and hung in pivotal connection with ears e of the plate is crank-dog N, that plays in said aperture and engages the rack I aforesaid.

The bars J, their horizontally-disposed arms K, the rod L, and plate M constitute a block-rest frame that is readily adjustable in a vertical direction to support a block thereon in position to be acted upon by the knifedisk of the machine, said block-rest being held in its adjusted position by an engagement of the dog N with the opposing rack. By taking hold of the rod L the block-rest may be lifted to a desirable elevation, the dog N catching in the rack H to maintain the adjustment. To lower said bloclcrest, the same is lifted slightly and the do N disengaged from the rack H by a foot of the operator, after which the desired adjustment is effected and said dog again permitted to engage said rack.

Machines of the kind above noted are ordinarily provided with block-rests in the form of brackets bolted in adjusted position, and

to vary the adjustment of such block-rests requires an undesirable expenditure of time that may be saved by the employment of the novel construction and arrangement of parts herein shown and described in orderto accommodate the machine to blocks of varying diameter.

A block supported on the rest is turned by hand in contact with the knife-disk of the machine, the result being a shaving of the bark from said block.

While I have shown the locking-dog arranged to engage a rack on the front of the machine, other provision may be had with the dog for holding the block-rest in adjusted position.

I claim 1. A bark-rossing machine comprising a rotary knife-disk and having the front thereof provided with a vertical rack and guides, bars engaging the guides and having upper arms extending therefrom toward the operator of the machine, a rod connecting the arms, a lower apertured plate connecting the bars, and a dog hung in connection with the plate to play in the aperture of same and engage the rack.

2. A bark-rossing machine comprising a stand provided at the front with a vertical rack and guides, a frame having side bars thereof in sliding engagement with the guides and provided with horizontally disposed have hereunto set my hand, at Milwaukee, in block-supporting arms extending toward the the vcounty of Milwaukee and State of Wis- 10 operator of 1riihrilmfachine, a dog hung in OOilconsin, in the presence of two witnesses. nection wit t e rame to en a e said rac i, and a suitably-arranged rot ag knife-disk I EDWARD WILLIAM GOODRICK fast on a shaft for which said stand is pro- Witnesses: vided with bearings. N. E. OLIPHANT,

In testimony that I claim the foregoing I GEORGE FELBER.
